Why World Ag Expo 2027 Matters for Agricultural Equipment Engineers
World Ag Expo brings together agricultural equipment manufacturers, farmers, engineers, and industry professionals every February in Tulare, California. It’s a great opportunity to explore new products, meet technical experts, and discuss solutions for real-world agricultural applications.
Whether you’re designing tractors, sprayers, combines, planters, seeders, or irrigation systems, we look forward to meeting you and learning more about your projects.

Two Different Jobs: Pressure Switches vs. Pressure Transducers
Before specifying any pressure component for agricultural equipment, it is worth being precise about what each device actually does. The terms are often used interchangeably in the field — and that is a common source of specification errors. For a deeper look at the distinctions, see our guide on pressure sensors vs. pressure switches vs. pressure transducers.
| Function | Pressure Switch | Pressure Transducer |
|---|---|---|
| Output type | On/off switched signal (opens or closes a circuit) | Continuous analog or digital signal proportional to pressure |
| What it detects | Pressure crossing a set point | Actual pressure value across the full measuring range |
| Typical output | NO or NC electrical contact; PNP/NPN for electronic types | 0–10 V, 4–20 mA, CAN J1939, RS-485 |
| Typical agricultural use | Low/high hydraulic pressure warning, pump protection, circuit fault detection | Precision spray pressure feedback, machine network data, automated irrigation control |
A pressure switch does not report a pressure value — it detects when pressure crosses its switching point and changes the state of its electrical contact. A pressure transducer does not open or close a circuit — it converts pressure into a continuous signal a controller can read. Selecting the wrong type for a given function is one of the most common mistakes when selecting industrial pressure switches.
Pressure Switches for Agricultural Equipment
The hydraulic system plays an important role in tractors, combines, and sprayers. It controls many functions, including the hitch, lift arms, header drive, and steering. Pressure monitoring is also important for pumps used in water management and irrigation systems.
A pressure switch monitors pressure and responds when it drops below the switch’s set point. In a hydraulic system, this drop may indicate a leak, pump wear, or a blocked filter. When this happens, the switch opens or closes an electrical contact to turn on a warning light, shut down a circuit, or activate a safety function. The pressure switch works directly, without needing a controller to process pressure readings.
SUCO ESI North America offers mechanical pressure switches designed to handle tough agricultural conditions, including vibration from rough terrain, dust and debris during harvesting, and moisture from rain or equipment washdowns.
Available electrical connections include Deutsch DT04-2P and AMP Superseal 1.5, both sealed connectors commonly used in mobile equipment.
Built for Agricultural Hydraulic Systems
Pressure spikes are a routine part of agricultural hydraulic operation — every time a loader lifts a heavy bale or a planter engages its seeding drive, the system sees a transient pressure event. SUCO mechanical pressure switches are designed to handle these spikes safely, with overpressure ratings documented on each product’s datasheet.
For irrigation systems, pressure switches serve a protective function: they can detect when pump outlet pressure falls outside the acceptable range, helping protect pumps, valves, and downstream components from running dry or overpressure conditions. For more on this application, see our article on pressure switches for agricultural irrigation.
Selection Tip
When specifying a pressure switch for a tractor or combine hydraulic circuit, confirm the connector type used on the machine’s wiring harness before selecting a model. Matching the connector avoids adapters and keeps the connection sealed.

Pressure Transducers for Agricultural Equipment
Precision agriculture depends on data. A sprayer that adjusts nozzle output based on GPS position still needs accurate, real-time pressure data from the hydraulic and fluid circuits driving those nozzles. That is a transducer job. Unlike a pressure switch, a pressure transducer converts the actual system pressure into a continuous electrical signal — allowing the machine’s controller to modulate output, log data, or trigger proportional responses rather than simple on/off actions.
On modern agricultural equipment with CAN-based machine networks, a transducer with CAN J1939 output integrates directly into the vehicle’s data bus. The controller reads pressure as a live value alongside other machine parameters — engine load, GPS position, implement status — enabling genuinely automated process control. The SUCO ESI North America Series 0630 & 0631 CANbus pressure transducers are designed for exactly this architecture.
For applications using analog controllers or legacy systems, the Series 0710 pressure transducer provides a 0–10 V output signal — a widely compatible format for agricultural PLCs and display controllers. Understanding how these components integrate into broader hydraulic control systems is covered in our guide to mobile hydraulics in automotive and transportation.

Frequently Asked Questions
Where will World Ag Expo 2027 be held?
World Ag Expo 2027 will be held at the International Agri-Center in Tulare, California, February 9–11, 2027. SUCO ESI North America will be exhibiting at Booths 2022 and 2023.
How much does it cost to attend World Ag Expo?
Admission pricing for World Ag Expo is set by the show organizers and may vary by year. For current ticket pricing and registration details, visit the official site at worldagexpo.com. SUCO ESI North America does not set or control admission fees.
What is the difference between a pressure switch and a pressure transducer on farm equipment?
A pressure switch opens or closes an electrical circuit when hydraulic pressure crosses its set point — it produces an on/off signal used for warnings, shutdowns, or circuit protection. A pressure transducer converts pressure into a continuous output signal (such as 0–10 V or CAN J1939) that a controller reads as an actual pressure value, enabling proportional control and data logging. Both are used on agricultural equipment, but they serve different functions and should not be substituted for each other.
What types of agricultural equipment use SUCO pressure switches?
SUCO ESI North America pressure switches are used on tractors, combines, sprayers, planters, seeders, irrigation systems, and other hydraulic farm machines. They detect pressure changes in hydraulic circuits so that problems can be caught early and equipment damage avoided. Connection options include Deutsch DT04-2P and AMP Superseal 1.5 formats, which are standard on many agricultural OEM platforms.
